North Fork Clover Creek E1 Det Basin dam
North Fork Clover Creek E1 Det Basin
North Fork Clover Creek E1 Det Basin, located in Pierce County, Washington, is a crucial flood risk reduction structure designed by KCM Engineers in Seattle. Completed in 2000, this earth-type dam stands at a hydraulic height of 10 feet and a structural height of 8 feet, providing a maximum storage capacity of 170 acre-feet. The basin covers a surface area of 3 acres and serves a drainage area of 1.87 square miles, with a maximum discharge capacity of 749 cubic feet per second.
Managed by the Washington Department of Ecology, this high-hazard potential structure is regularly inspected every 5 years to ensure its fair condition and functionality. The dam's primary purpose is flood risk reduction, with a normal storage capacity of 40 acre-feet. While specific details about spillways, locks, and modifications are not provided, the dam's critical role in protecting the surrounding Parkland community from potential flooding events is evident. With its strategic location in the N Fk Clover Creek watershed, this basin plays a vital role in water resource management in the region.
As climate change continues to impact precipitation patterns and intensify extreme weather events, structures like the North Fork Clover Creek E1 Det Basin become increasingly essential for safeguarding communities and ecosystems against flooding risks. With its state-regulated status and adherence to inspection and enforcement protocols, this dam exemplifies the collaborative efforts between local governments and regulatory agencies to mitigate flood hazards and enhance water resource resilience in the face of a changing climate.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About North Fork Clover Creek E1 Det Basin
Where does the data for North Fork Clover Creek E1 Det Basin come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
